' UNITED STATES PATENT vori-ica` ARTHUR B.. MODINE, OF RACINE,WISCONSIN.

` TOBACCO PIPE.

.I'Application led December 6, 1923. Serial No. 678,901.

To all 'whom it concerne.;I f y Be it known that I, ARTHUR M onrnmacitizen of the` United States, residing at Racine, in the county ofRacine and State of VViscons-in, have invented certain Vnew and usefulImprovements 1n Tobacco Pipes, of whlch the followmg is a description.'

My invention relates to improvements intobacco pipes, and moreparticularly vto a pipe having means. for cooling the smoke.

passing therethrough so as to render the same most pleasmg tothetaste,and prevent burning of the tongue and mouth.

The invention has among its objects the'.

production of a device of the kind described, which is simple,convenient, com.-V

pact, durable, reliable, satisfactoryv and efficient for use whereverfound applicable.

Many l)ther objects and advantages of the construction herein shown anddescribed will. be obvious to those skilled'in theV art from thedisclosures herein given.

To this end my invention consists ingtlhe' novel construction,arrangement yand .coinbination of parts herein shown and i' de scribed,and more particularly pointed out in the claims. I

In the drawings, wherein like referenc characters indicate like orcorresponding parts,

Y Fig. 1 is a longitudinal sectional lviewl taken through one form of mydevice; y

Fig. 2 is a similar View showing a modified form;- Y

Fig. 3 is a section taken on the line 3-3 of Fig. 2; and Y Fig. 4 is asection showing another modified form.

In the drawings, wherein Ivhave illustrated the preferred embodiments'ofmy invention, there is shown in Fig. 1 a pipe' having ar bowl 1 hollowedout as at 2 to provide a tobacco-receiving chamber and Vhaving passages5 and 6 leading from said chamber to the exterior of the bowl.Thepassage 5 is substantially at the extreme bottom of the chamber,while the passage 6 is at a'higher elevation. A stem 3 having a ratherlarge bore 7 therethrough from one end,i`s fastened to the bowl and hasa pair of openings 5 and 6 through one end, to register with theopenings 5 and 6 through the bowl.

A mouthpiece 4: is removably fitted to the open end of the stem 3 andhas a draft passage S therethrough from end to end,

. said passage extending obliquely downoccurs those irritating noises orwardly from adjacent the upper end of that portion of the mouthpiecethat enters the bore 7 of the stem. p

In order lto cool the smoke passing through the pipe, the stem ispreferably made of metal andhas ribs or fins 9 extend- .ing about itsperiphery, so that these fins may serve to carry off and radiate or dis--sipate the heatl from the smoke passing through thek stem. The capacityof the chamber 7 is vmade sufficiently large so that it will hold asubstantially full puff of smoke so as to give the smoke a chance tohave its heaty absorbed or radiated before .passing through themouthpiece 4.

'In order to agitate the smoke passing through the cooling member andabsorb :or dissipate substantially all of the heat therefrom, a spiralmember or vane 10 is arranged in the chamber 7 so that the smokepassing'through the chamber will be conducted along a` spiral path sothat all of it will engage the wall of the stem 3.

The

spiral member 10 is preferably secured tov the mouthpiece 4 so that whenthe mouthpiece is removed the spiral member may. act. as a scraper toclean the stem 3.

In smoking a pipe, the bottom of the vbowl generally in time lls up withtobacco andjmoisture making a gummy or partly liquid substance, which Iterm the -slug, and it is sometimes difficult to prevent drawingparticles of this slug up through the mouthpiece when smoking the pipe.It is on account of this slug that there commonly urgling. In use, thepipe is generally heb? so that thev bowl is below the smokers mouth andtherefore, when using a pipe of my con'- struction, even though there isa slug at the bottom of the bowl, the smoke Willpass. through the upperport 6, moving spirally through the stem, and thence through themouthpiece. Any nicotine, vapors, or tobacco oils impinge on the wallsof the stem and spiral member, where they may con- ;dense and flow backinto the bowl through the lower duct 5. It is to aid in this purposethat the draft passage 8 is formed in the manner shown, that is, one endof the same communicates with the stem at` the upper part of the stemrather than at the center or bottom thereof.

In the form shown in Figs. 2 and 3, ithe stem part 11 has a draft'passage 12 therethrough lin registry with and of the same wound ametallic member having one flange which lies against the periphery ofthe stem and the other flange or rib 17 extending laterally of the stemand conducting the heat away therefrom.

Thus it is seen that I have provided a pipe in which the smoke is cooledduring its passage through the stem and in which any of the va ors oroils will be condensed when passing this cooling means, so that only thecool, dry smoke will be taken up by the smoker. y

Having thus described my invention. it is obvious that variousimmaterial modifications may be made in the same without de' partingfrom the spirit of my invention, ience I do not wish to be understood aslimiting myself to the exact form, construction, arrangement andcombination of parts herein -shown and described or uses mentioned.

Vhat I claim as new and desire to secure by Letters Patent is:

1. A tobacco pipe comprising a bowl, a metallic stem having tins forradiating the heat therefrom, and means for swirling the smoke outwardlyagainst said stem during its passage therethrough.

2. A tobacco pipe comprising a bowl, a metallic stem communicatingtherewith adjacent the bottom thereof,V and having integral Iins thereonfor radiating the heat of the smoke passing through the same, and aspiral vane extending longitudinally through said stem and swirling thesmoke outwardly during its passage through said stem.

3. A tobacco pipe comprising a bowl, a tubula'r metallic stem part withan enlarged bore therethrough, fins formed) inte ral with the stem forradiating the heat of t e smoke passing through the same, a mouthpieceextending from said stem and having its bore 'downwardly inclined fromthe top of said stem, said bowl having openings into said stem adjacentthe bottom and' top of the bore through the stem.

4. A tobacco pipe comprising a bowl, a tubular metallic stem with anenlarged bore therein. tins formed integral with the stem for radiatingthe heat of the smoke passing through the same, u spiral vane lextendinglongitudinally through the stem for swirling the smoke outwardly duringits passage through said stem, and a mouthpiece extending from said stemand having itsv bore communicating directly with the upper part of saidenlarged bore, said bowl having openings into said stem adjacent thebottom and top of the enlarged bore through the stem.

In testimony whereof, I have hereunto signed my name.
